I've never done an album like this. With Biophilia, I was being like Kofi Annan - I had to be the pacifist to try to unite the impossible. Maybe that was a strange, personal job between me and myself, to show how overreaching I was being as a woman. The only way I could express that was by comparing it to the universe.

I sometimes fall into the trap of doing what I think I should be doing rather than what I want to be doing.

I have always had a certain song in my head, a certain chemistry of sounds.

It's funny how the hippies and the punks tried to get rid of the conservatives, but they always seem to get the upper hand in the end.

What comes first? The melody, always. It's all about singing the melodies live in my head. They go in circles. I guess I'm quite conservative and romantic about the power of melodies. I try not to record them on my Dictaphone when I first hear them. If I forget all about it and it pops up later on, then I know it's good enough. I let my subconscious do the editing for me.

People ask me questions like, "Oh, you look so theatrical in your photographs. Is that what you're like when you walk down the street?" It's like, "Of course not." It's such a silly question - it's like being theatrical is a crime.

It takes a long time to fully become who you are.
